Resumo(s)
Stadia acoustics have seen tremendous evolution in the last decades. Ranging from their geometry and consequent impact on sound propagation to state-of-the-art sound system designs. In fact, the way sound will function in these stadia will have a profound impact on the spectators and surrounding community. It will influence the spectators’ enjoyment and determine the successful outcome of a newly inaugurated stadium, as it will reshape the soundscape its inserted in. Careful acoustical design will determine the quality of speech intelligibility in the advent of needed announcements and improve overall atmosphere. This dissertation will strive to understand past and current trends of stadia acoustics and engineering so we can understand where we are heading. We will be discussing the origins of the football stadium, its conceptual and construction phases, choice of materials and different installation approaches. These aspects will then be supported by diverse case studies made on stadia acoustical properties throughout these last couple of centuries. Several interviews were also conducted with experts in the field of stadia design and engineering so that their methodology and vision can be further discussed. A sustainable and environmentally friendly mindset is clearly a 21st century phenomenon and football stadia do not stray away from it. This is a predicted trend for future stadia design and also applicable to their acoustical capabilities.
